C:\Temp\C--Program Files-gretl-gretlw32.exe c--temp-conjoint3.txt was not found.

The text file is in its proper location. It seems that JMP does not like the second part of the string in the Open function. Is there a way to tell JMP to execute Gretl and read the text file? Is there a way to tell JMP that there's two parts to the string? What's wrong with the string I created?
